Last week we provided a fresh look at the AMD
Radeon Gallium3D performance using the latest development code for the Linux
3.0 kernel and Mesa 7.11 library. Today we are now looking at the Gallium3D driver
performance of the Nouveau driver that is reverse-engineered to support NVIDIA
GeForce graphics processors.
Testing in this article is quite simple, like last week's Radeon
Gallium3D tests. A NVIDIA GeForce 9800GTX graphics card was tested on NVIDIA's
proprietary Linux driver (the 275.09.04 beta release) against the Linux 2.6.38,
Linux 2.6.39, and Linux 3.0 (11 June Git) releases with the Mesa 7.11-devel Git
as of 11 June. The different kernels is to see whether the Linux 3.0 DRM (Direct
Rendering Manager) code for the Nouveau module has affected the performance at
all, for this GPU at least. The libdrm and xf86-video-nouveau DDX were also obtained
from Git on 11 June.
The rest of the test hardware included an Intel Core i7 990X Extreme
Edition "Gulftown", ASRock X58 SuperComputer motherboard, 3GB of system
memory, 320GB and Seagate SATA HDD. Ubuntu 10.10 was the base operating system
with the GNOME 2.32.0 desktop with Compiz, X.Org Server 1.9.0, GCC 4.4.5, and
an EXT4 file-system. Unlike the Radeon driver, the Nouveau driver does not have
any swap buffer wait and color tiling X.Org options to toggle for testing.
Benchmarking was done using the Phoronix
Test Suite and OpenBenchmarking.org,
where the results are stored as 1106115-GR-NOUVEAULI02.
